我有一个带有indexedDB的注册表单。我有resgister /登录工作。我一直在尝试不同的东西,一旦他们注册就可以获得一个新的注册登记,但我不确定会发生什么。它不会起作用。 localStorage设置它应该但它不会显示用户的数据。
JS:
function addObject(){
if(confirm('Are you sure you want to resgister?')){
fName = document.getElementById('fName').value;
lName = document.getElementById('lName').value;
userName = document.getElementById('uName').value;
pass = document.getElementById('password').value;
email = document.getElementById('email').value;
dob = document.getElementById('dob').value;
tel = document.getElementById('tel').value;
bio = document.getElementById('bio').value;
terms = document.getElementById('terms').value;
school = document.getElementById('school').value;
//Need loop to find radio button values
radios = document.getElementsByName('gender');
for (var i = 0, length = radios.length; i < length; i++) {
if (radios[i].checked) {
gender=radios[i].value;
}
}
//set up transaction
var mytransaction = db.transaction(['users'], "readwrite");
//get object store
var myusers = mytransaction.objectStore('users');
//Add item
var request = myusers.put(new getUser(userName,fName,lName,pass,email,dob,tel,bio,terms,school,gender));
}
// Show all results.
if(document.URL.indexOf('admin.html') > -1){
mytransaction.addEventListener('complete', showUsers);
}
//Log in new users
loginCheck(userName,pass);
/*newLocal('user',user); */
//Reset Form Fields
resetForm();
}
这是我登录时使用的功能。
function loginCheck(user,pass){
db.transaction("users").objectStore("users").get(user).onsuccess = function(e) {
var loggedUser = e.target.result;
if(!loggedUser){
alert('Sorry, Username does not exist. Please try again.');
}else if(pass !== loggedUser.pw ){
alert('Incorrect log in combination. Please try again.');
}else{
loggedIn(loggedUser);
populateFields(loggedUser);
loginStyle(loggedUser)
}
}
}
function loggedIn(loggedUser){
var u=loggedUser;
alert('Welcome '+u.fn+' '+u.ln+' to Macroplay');
//Set localStorage
var signedin = 'user';
var username = u.userName;
newLocal(signedin,username);
}
function getValues(){
db.transaction("users").objectStore("users").get(localStorage.user).onsuccess = function(e) {
populateFields(e.target.result);
loginStyle(e.target.result)
};
;
}
从我所看到的第一部分将用户添加到数据库中,第二部分应该像我刚刚正常记录一样。但它不会从数据库中获取信息。
我已经尝试将新用户设置为localStorage,这是我如何识别当前登录的用户,但也没有效果。

看起来你在onsuccess
方法中使用了loginCheck
处理程序,但是在数据库上调用put
时却没有。我的猜测是你在实际有机会被添加之前检查用户是否存在。试试这个:
//Add item
var request = myusers.put(new getUser(userName,fName,lName,pass,email,dob,tel,bio,terms,school,gender));
request.onsuccess = function () {
// Show all results.
if(document.URL.indexOf('admin.html') > -1){
mytransaction.addEventListener('complete', showUsers);
}
//Log in new users
loginCheck(userName,pass);
/*newLocal('user',user); */
//Reset Form Fields
resetForm();
}
